NEW YORK, N. Y.

SHEET-DELlVERY APPARATUS.

SPECIFICATION forming part of Letters Application filed February 25, 1884.

To all whom it may concern.-

Be it known that I, LUTHER C. ORowELL, a citizenof the United States, residing in the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Sheet-Delivery Apthe following specification and the accompanying drawings, forming a part of the same.

This invention relates to amechanism which is designed to operate .in connection with a web into sheets and deliver the same, either singly or associated into lots of two or more, with either one or two transverse folds, it being the obj ect of the invention to provide a simple and reliable delivery mechanism for use in those printing establishments which desire to issue papers which vary in volume and to deliver them folded to different dimensions.

To these ends the invention consists, broadly, of two cooperating rotating cylinders or carriers provided with cutting, collecting, and folding mechanisms, which are arranged to operate in such manner that the sheets severed from the aveb may be collected into lots of two or more, and then folded once or twice transversely, or that said sheets may be operated upon singly and folded in either of said ways.

The invention also embraces various details of construct-ion in the mechanisms just speciplained, and particularly pointed out.

In the accompanying drawings, Figure l is a sectional elevation of the main cylinders'and their co-operating folding -rolls, the framework for supporting the parts being omitted, as the same can be readily supplied by any ordinarily skillful mechanic. Fig. 2 is a similar view showing the parts in a different position. Figs. 3, 4, and 5 are enlarged sectional details illustrating the construction and operation of the mechanisms for making the first fold, said mechanisms being shown in different positions .in the several figures. Figs. 6 and '7 are like views illustrating the construction and operation of the mechanisms for making the second fold, said mechanisms'being shown indifferent positions in the two figures. Figs. 8, 9, 10, and 11 are like'views illustrating the construction and Patent No. 316,123, dated April 21, 1885.

(N0 model.)

operation of a modified form of the mechanisms for making the first fold, said -mech anisms being shown in different positions in the several figures; and Figs. 12 and 13 are like views illustrating the construction and operation of a modifiedforni of the mechanisms for making the second fold, said mechanisms being shown in different positions in the two figures.

Referring particularly to Figs. 1 and 2, it is to be understood that the mechanism embodying the present invention consists, essentially, of two revolving cylinders or carriers, 98 99, which are of a circumference at least equal to the length of the sheet which is to be operated upon, and are geared together or otherwise connected so as to be driven at the same surface-speed, and a pair of folding-rolls, 96 97, which are geared to each other and to the cylfinders in the usual manner. These cylinders and rolls are provided with cutting, collecting, and folding mechanisms, which are con structed and arranged as follows: The cylinder 99 is provided with a cutting-groove, 95,.

spring-seated cheek-pieces, 9, which project slightly beyond the periphery of the cylinder upon each side of the blade, so as to-press the paper against the cylinder 99 and hold it stretched across the groove at the time the cutting takes place.

The bar 94, in which the cutting-groove 95 is formed, is made to project slightly beyond.

the periphery of the cylinder 99, so that as the blade and groove come into co-operation the. walls of the groove will-press the paper slightly within the periphery of the-cylinder 98. By this means the blade is caused to pass through the paper a suificient distance to insure a clean and perfect severance without the necessity of making the blade project but a slight distance beyond the periphery of its cylinder.

Just in the rear of the blade 93 the cylinder 98 is provided with a set ofimpaling-pins, 10,

which are pivotally secured to the ends of a series of -arms, 11, extending from, ayrockshaft, 12, journaled in the heads of the cylinder in the usual manner. These pins are protruded and retracted to impale and release the leading ends of the sheets in the following manner: The shaft 12 is provided with a rockarm, 13, to which is connected one end of a rod, 14, the opposite end of which is connected to a rock-arm, 15, extending from a second rock-shaft, 16, also journaled in the heads of the cylinder, and provided with a second rockarm, 17-, having a stud, -18, which, as the cyl inder revolves, is engaged by a rotary cam, 92, which is secured to the face of a gear, '90, mounted upon a short shaft or stud, 91, and engaging'with a gear, 89, of 01161131 its size mounted upon the shaft 88 of the cylinder. The movement of the pins in the opposite ,direction is'effected by means of a spring, 19, which is confined between a collar upon the rod 14 and a projection upon the cylinderhead.

The cylinder 99 is provided at a point opposite the cutting-groove 95 with a rock-shaft, 20, upon which is mounted anipping-jaw, 21, which extends the length of the cylinder, and is curved so as to be of about the shape of an ordinary sheet-gripper, so that when operated to grasp the sheet its nipping-edge passes through a longitudinal opening, 23, in the cylinder, and closes down upon the slightlydepressed portion 22 of the cylinder in the rear of the opening 23 in substantially the same manner as an ordinary sheet-gripper, The jaw 21 is closed to grasp and hold the sheets by means of a spring arranged upon the shaft 20, in the usual manner, and a stationary cam, 85, which engages with a stud, 25, projecting from a rock-arm, 24, extending from the-shaft 20, and is opened to receive and re lease the sheets at the proper times by means of a stationary cam, 86, which also engages with the stud 25. The cam 86 is madein two parts, 50 51, as indicated by the dotted lines in Figs, 1 and 2, the part 50, which is provided with the projection 7 for opening the jaw to receive'the sheets, being fixed, while'the part 51,wh ich is provided with the projection 8 for opening the jaw to release the sheets, is adjustably secured to the part 50 by means of the bolt 26, passing through the slot 27, so that the projection 8 can be shifted in position, and

thus cause the jaw to be opened to release the sheets at different points in the revolution of the cylinder, as will be more fully described when the operation of the mechanism is explained.

A-short distance in the rear of the opening 23 the cylinder 99 is provided with a second longitudinal opening, 5, in which is journaled a small rock-shaft, 4, to which is, secured a number of fingers or a thin plate, 3, which extend forward so as to lie just abovea-recess, 6, formed in the depressedportion 22, upon which the jaw 21 closes. The shaft 4 is provided with a suitable spring or springs, which serve tohold it normallyin such position that the plate or fingers 3 will project somewhat beyond the periphery of the cylinder, as shown in Figs. 1 and 2.

The rock-shaft 16, which has already been mentioned in connection with the cylinder 98, is provided with a forwardly-extending tucking-blade, 29, which lies in a longitudinal opening, 30, in the cylinder, in such position that as the cylinders 98 99 revolve and the stud 18 is brought into engagement with the cam 92, so as to rock the shaft 16, the forward edge of the blade will be thrown outward beyond the periphery of the cylinder 98 and come into engagement with the plate 3, so as to depress said plate into the recess 6 and be caught beneath the end of the jaw 21 as it is closed-by the cam 85. k

The cylinder 99, in addition to the'features already described, is provided at a suitable distance in'the rear of the jaw 21 with a 10ngitudinal opening, 31, in which is journaleda shaft, 32, carrying an ordinary rotating folding-blade, 33, which acts in the usual manner to fold the sheets from the cylinder into the bite of the rolls 96 97.

The blade 33 is operated in the following manner: The shaft 32 upon which the blade is mounted is provided at one end with the usual cross-head, 34, the opposite ends of which are provided with outwardly-projecting studs 2,

and the shaft of the folding-roll 97 is provided with a revolving disk, 36, in the face of which is formed a cam-groove, 37. The parts are so timed that as the forward edge of the blade arrives in position to fold the sheet off the cylinder the stud 2 of the forward arm of the cross-head 34 will enter the forward end of the cam-groove 37,-and thus as the cylinder and roll continue their revolution this-stud will remain in the groove until the blade has completed nearly a half-revolution and folded the sheet into the bite of the rolls 96 v97. As the stud passes out of the rear end of the groove 37 it will come into engagement with the stationary canr38, which will causethe 1 blade to complete its half-revolution and bring I the stud upon the other arm ofthe cross-head to the front and into position to enter the came groove 37 upon the next revolution ofthe-cylinder. i

. The remaining features of construction in i the mechanism just described will bereferred to in connection with the explanation of its operation, which is as follows: The web of paper, having been perfected by any suitable form of web-printing mechanism, will be entered into the bite of the cylinders 98 99 insuch position that its leading end will be impaled upon the pins 10 and carried around upon the surface of the cylinder 98. As the cylinders 'continuetheir revolution and arrive at the position shown in Fig. '3, the stud 25-of the rock-arm 24 will come into engagement with the projection 7 of the cam 86, so-as to open the jaw 21, and at the same time the stud '18 4 of the rock-arm 17 will come into engagement with the cam 92, so that as the cylinders continue to advance from this position the pins jaw 21 over onto the paper and the edge of the blade 29, and thus grasp the paper upon the fold-line, as shown in Fig. 4. As the cylinders continue their revolution from this point the blade 29 will be withdrawn, as shown in Fig. 5, so as to leave the fold of the paper in the bite of the jaw 21 and the plate 3, and cause it to be carried forward upon the cylinder 99.

It will be observed that after it is folded, as just described, the sheet is held by the jaw 21 in such position that there is no abrupt bend in the sheet just in the rear of the fold-line, as is the case where the portion of the sheet held by the nipping-j aws extends inward toward the axis .of the jaw-cylinder. This is a desirable feature, as it permits the sheet to be more readily stripped from the cylinder at the proper time. The first transverse fold having been .made in the manner just described, the fold will be held by the jaw 21 and carried around upon the cylinder 99 until the blade 93 and groove 95 come into co-operation,when the first sheet will be severed from the web, and at the same time the freshly-cut end of the web will be impaled upon the pins 10, as already described. As the parts arrive in the position shown in Fig. 6, the stud 2 upon the forward half-revolution, so as to fold the sheet into the bite of the rolls, as shown in Fig. 7, and thus the second transverse fold will be made. As the cylinders continue their revolution from the position shown in Fig. 1,the stud 25 of the rock-arm 21 will again come into engage.

ment with the projection 7, and the operation just described will be repeated. As the sheets emerge from the rolls 96 97, they may be conducted to any suitable folding mechanism, to be further folded, or directly to a piling mechanism.

If it should be desired to associate the sheets in pairs beforethey are folded, it can be done by simply removing the part 40 of the cam 92, so that the pins 10 and blade 29 will be operated only at each alternate revolution of the cylinder 98. When this is done, the first sheet taken by the pins will be carried around upon the cylinder during one revolution and v have the second sheetimposedupon it, after which, upon the second revolution of the cylinder, the two sheets thus associated will be folded off the cylinder together, and will then receive their second fold and be delivered in the manner already described.

Instead of two, three or more sheets may be associated and folded in the same manner by making the cam 92 of proper form, and so proportioning the gears 89 90 that the cam will make but one revolution to three or more of the cylinder.

If it should be desired to impart only one instead of two transverse folds to either the single or associated sheets, it may be done by simply shifting the part 51 of the cam. 86 to the position shown in Fig. 2, and bringing the guides or switches 39 into position. to .direct the sheets between the rolls 96 97 without being folded. When this'is done, the jaw 21 will be opened so as to release the folded edge of the sheets just before they arrive at the bite of the rolls 96 97 and as soon as this takes place the plate or fingers 3 will move outward, so as to direct the end thus released between the guides 39 and'the roll 97, as indicated in F1 2. i.

I t is of course to be understood that the web before passing to the cylinders 98 99 to be operated upon, as just described, may receive one or more longitudinal folds, or may be IOO It is to be remarked in conclusion that many modifications may be made in the details of the mechanism herein described without departing from the invention. Figs. .8 to ;11 illustrate one such modification in the mechanism for forming the first fold. In this con struction the portion 22 of the cylinder, upon which the jaw 21 closes, is not depressed be.- low the remaining portions of the cylinder, so that the jaw in closing passes into the opening 30 of the cylinder 98, as shown in Fig. 10. -The recess 6 is also, as will be observed, somewhat modified in form, so that the paper has a slightly more abrupt bend just in the rear of the fold. Fig. 8 shows the parts of this modified construction in the position they will occupy just after the jaw 21 is opened; Fig. 9, in the position they will 00- cupy just after the blade 29 has been rocked outward; Fig. 10, in the position theygwill occupy just after the jaw 21 has been closed,

and Fig. 11, in the position they will occupy just after the blade 29 has been withdrawn ciated'shets, all substantially as described.

38 is omitted, and the cam-groove 37 in the disk 36 is 'madevery'much shorter than in the construction first'described. The shaft of the roll 96 is, however, provided with a disk, 42, in which is formed a cam-groove, 41, said disk and'cam-groove being so positioned'that as 'the'stud 2 ofthe cross-head 34 passes out of thegroove 37 it will enter the groove 41, in

whichit will be retained until the blade has completed its one half-revolution.

Fig. 12 shows the parts in the positionsthey "willoccupyjust as the stud 2 enters the groove 37, and Fig. 13 shows'the' parts in the positlOllS they will occupyjust as the stud 2 is leaving the'groove 37.

In either'of the constructions shown the jaw 3 21, instead'of extending the entire length of the cylinder, maybe made of a number of; short'sections arranged at a suitable distance [from each other upon the shaft 20.
